The Hamilton Smart phone holder with tube clamp keeps that all-important conduit to society with life's essential apps right where it's most useful. The unique and simple scissor-action clamp is strong enough to hold the smartphone securely at all times. The high friction yet gentle clamp posts will accommodate a wide variety of smart phones, while giving clear access to touch screens, buttons and ports. The Smartphone Holder is packaged with a discreet tube clamp that will securely attach to any 5/8" to 1" diameter stand tube (think cymbal, music or mic stand). To complete the package there's a 6" gooseneck to position the holder ergonomically, in just the right spot for viewing, texting, editing, recording or jamming.
